dont really know why this is happening,but normally when i connects my headphones to the laptop(i use the laptops soundcard right now)i only heard the sound in the headphones(like its suppoesed to work)
but now when i connect my headphones i also hear the sound on the laptop speakers??
does any1 know a way to fix this??
You could go over the connector on the motherboard with a soldering iron and hope it’s a dry joint but chances are it’s buggered. Have the same issue with one of the desktops in the workshop at work.
You guys both have the exact same amount of posts! Now when one of you posts, the other has to too, to keep this consistent 
mines done that a couple o times too, dont know how i fixed it, probably installed drivers again or something.
